Mr. John McCarthy:

As stated earlier, we are migrating from phase 1, which was a much lower cost programme, to phase 2. I have acknowledged very clearly that the costs will be higher. As our capital ceiling increases in the years after 2019, I expect that figure will increase and that will accelerate the momentum in the phase 2 programme. Apart from phase 2 and NZEB, the NPF is obviously designed at a very high level to be the strategic driver to underpin much of the progress. I accept that we will need to rely on other Departments to deliver on it. If we did not have it as a strategic planning framework, however, our climate change challenge would be considerably greater.
